  Ah, but they are pterosaurs, as you said. That's all I'm saying.

  If one is a category, so is the other. Sauropods are as diverse if not more
so than all of pterosaurs, so there is no reason to dismiss one group for
another. They are neither equivalent "ranks" nor are they unequivalent
"clades". They simply are groups.

  Cheers,
